Washington, United States, 1968.

She began her art studies in the MCPS Art Center in Maryland between 1982 and 1986. She studied in the School of Visual Arts in New York, BFA New York in 1990. She completed a Fine Arts program in the Hunter College in New York between 1991 and 1992.

First of all, Ruyter photographs ordinary landscapes, street scenes or day-to-day events. She projects the slides onto large framed canvases in order to extract graphic compositions from them that lack any narrative element. On many occasions the view is frontal and uses extremely simple lines to organise the background. As she explains herself, she instinctively applies the colour. The use of ink urges the selection of the next colour and so on until the canvas is completed and saturated.

She admits that her chromatic choices subconsciously cause stress and that her point of view specifies the reading of her work for the spectators.

She uses the technique known as Block colour, an expression that is often used by print veterans to describe a simple effect: extending a block of colour before adding a silhouette or half-tone on top. The technique is as old as paint itself, but it forms part of Fine Arts thanks to the work of Andy Warhol and Pop Art.

Ruyter's paintings are indebted to Warhol, particularly the last portraits, where large areas of colour are abundant. The large areas of deep ink, intense orange, yellowish green, collide with each other as if they were tectonic plates.

She has given classes in Columbia University and the Academy of Fine Arts in Vienna, 2011 - 2012. She co-directed a gallery team in New York. She moved to Vienna and opened another gallery there.

She has been featured in over 25 solo exhibitions. Her work is exhibited in: the Colection of Melva Bucksbaum and Raymond Learsy, Sharon CT; the Denver Art Museum, United States; Sammlung Essl, Klosterneuburg in Austria; the Jumex Collection in Mexico; the Museum der Moderne in Salzburg; the Museum of Modern Art in New York; the San Francisco Museum of Modern Art and the VAC collection (Contemporary Art Valencia), Valencia, Spain.

She currently works in New York and Vienna.
